feat: Project Genie + Nano Banana concept pack for The Nexus (closes #680)
Complete concept generation pipeline:
- shot-list.yaml: 17 shots across 5 priorities (environments, portals, landmarks, skyboxes, textures)
- prompts/: 5 YAML prompt packs with 17 detailed generation prompts
- pipeline.md: Concept-to-Three.js translation workflow
- storage-policy.md: Repo vs local split for binary media
- references/palette.md: Canonical Nexus color/material/lighting spec

All prompts match existing Nexus visual language (Orbitron/JetBrains,
#4af0c0/#7b5cff/#ffd700 palette, cyberpunk cathedral mood).
Genie world prompts designed for explorable 3D prototyping.
Nano Banana prompts designed for concept art that translates to
specific Three.js geometry, materials, and post-processing.
